CHURN.

SPECIFICATION forming part of Letters Patent No. 366,055, dated July 5, 1887.

Application filed September 28, 1856. Serial No. 214,716. (No model.)

To all whom. may concern,.-

Be it known that I, MILns WILBUR, ol Palinyra, in the county of Jefferson, and in the State of Wisconsin, have invented certain new and useful Improvements in Ohurns; and I do hereby declare that the following is a full, clear, andeXact description thereof.

My invention relates to churns, being `designed as an improvement on the device `for which I obtained Letters Patent No. 346,697., dated August 3, 1886; .and it consists in certain peculiarities of construction,to be hereinafter described with reference to the aecompanying drawings, in whieh- Figure l represents a perspective view of a churn embodying my invention; Fig. 2, a detail view, partly in section,illustrati ng the construction and application of my device; Fig. 3, a horizontal section on line'm zr, Fig. 2; and Fig. 4,a detail illustrating the'inanner of packing the horizontal pipe of my device.

Referring by letter to the drawings, A rep resents a churn-barrel journaled in a suitable frame, B. One of thejournals C ofthe barrel is centrally perforated, as is also the adjacent head l) of said barrel, as shown in Fig. 2, to

permit the passage of a horizontal pipe, E, the latter being coupled at its inner and outer ends to vertical pipes F G. The horizontal pipe E also passes through a disk, Il, of metal, hard wood, or other suitable material, that is in tended to be held upon the inner side'of the barrel-head D by screws, this disk being hollowed out upon the side that comes adjacent to said barrel,so as to present edges c, that are embedded in the wood of the latter part when the screws are tightened, thereby aiding to secure a tight joint. The disk H has a hollow extension, H, that is externally provided with screw threads b, to engage corresponding threads, c, upon the interior of a cap, l.

I have found that the elastic packing employed in the device covered by my former patent was liable at times to become heated and stick to the horizontal pipe E, thereby preventing the revolving of the churn-barrel A, and to overcome this defect I now employ a suitable cord, J, which I wrap about said pipe to till such space that may exist between the latter and the central extension, II, of the disk I-I, leaving a portion of the cord beyond the inner terminus of said extension to be compressed by the screwing up of the cap I, thus forming a tight joint Abetween the parts that will not interfere with the proper working of the churn.

Instead of the two opposing arms pivotally connected to the churn-frame to forni tongs for securing the horizontal pipe E against turning, as described in my former patent, I elnploy a single rigid arm, K, that is removably secured to a stud, d, on said chmni'ralne by a screw, e, or other suitable means. For a een tain distance from its top the arni K is pro vided 4with a narrow slit, e, and on each side of this slit said arin is suitably recessed, as shown atf, to receive the pipe E. An angular brace, L, made from a single piece of metal,

is provided with a sleeve, g, that surrounds the outer vertical pipe, G, and lateral wings 7L, that bear against the inner side of the arm K when the main portion of this brace is inserted in the slit e of said arm, this construc- A tion and arrangement also serving as a means to retain the horizontal pipe in its proper position. The pipe E and brace L having been placed in posit-ion with relation to the arln K, i

the parts i of the latter are clamped together by suitable screws, k, the lower one of which impinges against saidpipe, thus. forming an additional means to prevent the saine from turning.

The vertical pipe F, that comes within the churn-barrel, is bent to forni a goose-neck, rn, at its upper end, as shown by Fig. 2,. and to this bent portion is screw-threaded or otherwise suitably secured an inverted-cup-shaped shell, M, the hollow central part, n, thereofl being downwardly extended. From the shell M is suspended a cone-shaped shield, N, that has its apex just below and inline with the mouth of the hollow part a, -this shield serving to prevent the contents of the churn from splashing up into said shell. rlhe upper end ofthe outer pipe, G, rises above that of the inner pipe, F, and is preferably provided with a funnelshaped cup, p, to facilitate the entrance of water when it is desirable to cleanse the churn, and the l-coupling r, that connects the horizontal pipe Fl with said outer pipe, is open at its bottom to receive asuitable plug, P.

It will be noticed that the horizontal pipe E TOO is about one-half the diameter of the vertical ones, F Gr, and this construction is designed to prevent the escape of the contents of the churn-barrel during the operation of churning without interfering with the iiow of the gas generated by such operation, it having been found that when all the pipes had the saine diameter, as Shown in my former patent,

' F, will be stopped at the point, s, where this latter pipe is coupled to the horizontal one, E, as, owing to the difference in their diameters, a shoulder is formed that, while impeding the passage of such particles, will not prevent the escapeof the gas, but rather aid the same, for

'the reason that said gas is compressed into smaller volume on entering said horizontal pipe, and then suddenly expanded when it enters the outer pipe, G, the compression of the gas also acting to 4retard said cream or butter particles that may find their way into said inner pipe.

While I have described the horizontal pipe as preferably of smaller diameter than the vertical ones, I do not wish to be understood as broadly claiming such feature, as I am aware of a rotary churn having one of its journals provided with a longitudinal aperture that registers with a short tube telescoped in a iixed vertical tube upon the interior of the churn-barrel, this latter tube having a greater diameter than said aperture and short tube.

l The general operation of my gas escape is in effect similar to that described in my former patent, and is cleansed in a like man ner to that set forth in said patent, while at the same time, though I have shown the device in connection with a revolving churn, it is equally applicable to any style of churn in use.

Having thus fully described .my invention, what I claim as new, and desire to secure by Letters Patent, is

1. rIhe combination, with a churn-barrel, of

, a gas-escape that comprises a stationary horizontal pipe extended into said barrel, inner and outer vertical pipes coupled to the respective ends of the horizontal one, means for preventing the entrance of cream and butter particles into the open end of the inner vertical pipe, and a packing that consists of a suitable disk having a hollow central extension, a suitable cord wrapped on said horizontal extension, and a cap to engage the hollow eXtension, substantially as and for the purpose set forth.

2. The combination, withachurn-barrel, of i a gas-escape that comprises a suitably-packed horizontal pipe extended into said barrel, inner and outer vertical pipes coupled to the respective ends ofthe former, means for preventing the entrance of cream and butter particles into the open end of the inn-er vertical pipe, a slitted arm rigidly secured tothe churn-frame and provided with a bearing for the horizontal pipe, and means for clamping the upper portions of said arm, substantially as and-for the purpose set forth.

3. The colnbination, with achurn-barrel, of a gas-escape that comprises a suitably-packed horizontal pipe extended into said barrel, inner and outer vertical pipes coupled to the respective ends of the former, means for preventinner vertical pipe coupled at its lower end to the horizontal one and its upper end bent in Athe form of a goose-neck, an inverted-cupshaped shell having a hollow downwardly-extended central part secured to said goose-neck, and a cone-shaped shield suspended from the shell, an outer vertical pipe coupled to said horizontal one, and means for retaining the last-named pipes in their normal position, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Palmyra, in the county of Jefferson and State of Wisconsin, in v the presence of two witnesses.
